what does Quartus message 142008 "Node xxxxx is a complex I/O" mean

Question

I recompiled a design last compiled under licensed Quartus ver ​17.x using Quartus Prime Lite 18.1.0 and get warning 142007 "Exported design partition includes one or more complex I/O elements".   And then it lists virtually  every pin as warning 142008 "Node xxxxxxx is a complex I/O".    Should I be concerned?  Any recommendations?  TYVM

Hi Fred,
Refer the below links &amp; if required, make the virtual pin assignments to the specified pins to make error free partition merge of the top level design.
